Adapter for filling fuel burning lighter

ABSTRACT

The present invention provides an adapter for interfacing between a reusable gas refill container and a refillable lighter, an apparatus for engaging a reusable gas refill container and an apparatus for engaging a refillable lighter. The adapter includes a body and an aperture defined by the body, wherein the aperture is sized to receive an ejection port of a gas refill container. The body also includes a threaded portion that mates with a threaded portion of the refillable lighter.

BACKGROUND OF THE INVENTION

[0001] This invention relates generally to gas-fired lighters and moreparticularly to the refilling of such gas fired lighters.

[0002] Refillable gas-fired cigarette, cigar or pipe lighters exist thatrequire specially designed refill containers. In certain instances,those specific gas containers provide a single or limited number of gasrefills and are relatively expensive. While sources of lighter fuelexist that hold refill fluid at higher pressures and that would providemore refills, those higher pressure sources have ejection ports that arenot compatible with lighters requiring a specific type of refillconnection.

[0003] In one example, a known lighter manufacturer produces a lighterhaving a refill connection with a threaded bore. For refills, thatlighter requires a specific refill container having a matching malethread. Standard, relatively inexpensive and relatively high pressurelighter fluid sources will not seal against the threaded bore of theabove-described lighter. Those refill containers cannot therefore beused currently to refill the above-mention lighter.

[0004] At least one attempt has been made to provide a “universal”multi-refill device, i.e., a device capable of being used to refilldifferent lighters. U.S. Pat. No. 3,940,015 provides a cover that fitsover a gas refill container and holds a series of adapters. The adaptersare sized differently to operate with differently sized inlet valves ofvarious lighters. The device of that patent appears to be sized to fitonto a particular refill container, and the adapters of the deviceappear to be sized to operate with the tube or ejection port of thatparticular refill container. The patent is therefore limited in thoserespects.

[0005] In a similar manner, the Swiss lighter company, Caran d'Ache,produces commercially a gas refill container with an adapter that fitssnugly onto the exit nozzle of the container. The adapter enables therefill container to operate with lighters made by Caran d'Ache. Thatadapter is intended to sell the company's expensive, low pressure refillcontainer and will not operate with lighters made by other companies.Further, it is believed that the adapter will not operate with refillcontainers made by other companies. The adapter does not enablerelatively inexpensive, high pressure lighter refillers to be used torefill cigarette, cigar or pipe lighters.

[0006] A need exists for a device that allows higher pressure refillcontainers to operate with lighters that require a specific or threadedconnection. Also, a need exists for a device that enables higherpressure refill containers having differently sized ejection ports tooperate with lighters having specific inlet valve configurations.

SUMMARY OF THE INVENTION

[0007] The present invention relates to refillable lighters and moreparticularly to an adapter or fuel transmitter that enables higherpressure gas refill containers to operate with lighters having inletvalves that have been previously incompatible with those refillcontainers. In one aspect therefore, an adapter for a gas-firedrefillable lighter is provided. The adapter includes a body that definesan aperture on one end. The aperture is sized to receive an ejectionport of the gas refill container. On the other end, the body defines athreaded portion that is sized to mate with a threaded portion of therefillable lighter.

[0008] The threaded portion of the body can be male or female to operatewith lighters that define female/male threads. In one embodiment, thebody is metal and has metal threads, although the body may alternativelybe plastic, wood or ceramic and define plastic, wood or ceramic threads.

[0009] The adapter or transmitter includes a seal that sealingly engagesthe gas refill container. An aperture housing the seal is sized toreceive variously sized ejection ports of different refill containers.The seal is made of a compressible material that deforms and sealsaround the variously sized ejection ports. In one embodiment, theaperture includes or defines a portion that is wide enough to accept anO-ring type of seal. In that case, the ejection port extends through theO-ring so that the O-ring seals between the outer cylindrical surface ofthe ejection port and the inner cylindrical surface O-ring of theadapter.

[0010] In another embodiment, an O-ring is provided that seals between aflange portion of the refill container (from which the ejection portextends) and an outer flat surface of the adapter.

[0011] In any case, the body of the adapter includes a threaded orattachment portion and a flanged or grasping portion that is adjacent tothe threaded portion. The flange portion in one embodiment is wider thanthe threaded portion so as to provide a surface that is readily graspedand turned by a person to insert or remove the adapter into or from,respectively, the lighter. In another embodiment, the adapter includes a“low profile” flange that inserts into the lighter on a permanent orsemi-permanent basis via the use of a tool, such as a hexheadscrewdriver.

[0012] In another aspect, the present invention includes an apparatusfor engaging a gas refill container. The apparatus includes a refillablelighter and an adapter that is removably attached to the lighter. Aperson can grasp either the lighter or the adapter and move thecombination, wherein the adapter cannot and will not slide with respectto the lighter and thereby become unattached from the lighter. Theadapter includes a portion that allows the adapter and lighter tooperably engage the gas refill container.

[0013] In one embodiment, the adapter is removably threaded onto thelighter. In one embodiment, the adapter is removably coupled to a bottomportion of the refillable lighter.

[0014] In still another aspect of the present invention, an apparatusfor engaging a refillable lighter is provided. The apparatus includes agas refill container. An adapter is operably coupled to the refillcontainer via an aperture that is substantially centrally located withinthe adapter. The refill container has an ejection port that extendsthrough the aperture to the refillable lighter. The ejection portcontacts the inlet valve of the refillable lighter to open that valveand the ejection port. That action allows the pressure of fluid withinthe lighter and the refill container to equalize, e.g., to “fill” thelighter.

[0015] In yet another aspect of the present invention, a method forenabling a person to refill a lighter is provided. The method includesproviding an adapter that attaches to the lighter so that a refillcontainer can insert through the adapter, contact the lighter, andsupply gas to the lighter. The method also includes enabling the personto remove the adapter from the lighter after use so that the adapter canbe reattached to the lighter at a later point in time.

[0016] In one embodiment, the person is enabled to thread the adapteronto the lighter. In another embodiment, the adapter is structured sothat the refill container can be inserted through the adapter to engagethe lighter.

[0017] In still a further aspect of the present invention, a method forgenerating revenue is provided. Here, an adapter is sold that attachesto a lighter and allows a refill container that would otherwise notoperate properly with the lighter to at least partially refill thelighter.

[0018] In view of the above non-inclusively described aspects of thepresent invention, it is an advantage of the present invention toprovide an adapter that allows a refill container to at least partiallyfill a lighter.

[0019] It is another advantage of the present invention to provide anapparatus that operably couples to and communicates with the fuelcontained in a refill container.

[0020] It is a further advantage of the present invention to provide anapparatus that operably couples to and provides fuel to a refillablelighter.

[0021] Moreover, it is an advantage of the present invention to enablehigher pressure refill containers to operate with certain refillablelighters.

[0022] It is still another advantage of the present invention to providean adapter that operates with differently sized refill containers.

[0023] It is yet a further advantage of the present invention to providean adapter for a cigarette, cigar or pipe lighter that may be usedrepeatedly to refill the lighter and that may remain permanently orsemi-permanently attached to the lighter.

[0024] Additional features and advantages of the present invention aredescribed in, and will be apparent from, the following DetailedDescription of the Invention and the figures.

DETAILED DESCRIPTION OF THE INVENTION

[0029] Referring now to the drawings and in particular to FIG. 1, oneembodiment of the overall apparatus of the present invention includes anadapter or transmitter 10, a refillable lighter 50 and a refillcontainer 100. The transmitter or adapter 10 is shown in cross-sectionfor purposes of illustration. A portion of front wall 52 of a housing 54of lighter 50 is cut away to illustrate how adapter 10 interfaces withlighter 50. A top portion of refill container 100 is illustrated. Therefill container 100 is mainly illustrated in cross-section toillustrate the inner workings of container 100. Adapter 10, lighter 50and container 100 each include an orifice that is centered along centerline 12 to show the alignment of the different components of the presentinvention.

[0030] Lighter 50 includes components of standard refillable lightersincluding the housing 54 and a lid 56 hingedly connected to housing 54.Lid 56 covers a rotatable friction-causing wheel 58 that creates a sparkwhen rotated against a flint (not illustrated) housed inside a flintcarrier 60. The user creates a flame via the frictional wheel 58 and theflint housed inside carrier 60 by turning roller 62. The turning ofroller 62 thus creates a spark that ignites a stream of gas, e.g.,butane, that exits from housing 54 to create the flame. The presentinvention is expressly not limited to lighters that use a flint butapplies to any type of lighter including lighters using piezo or quartzcrystal actuation.

[0031] Lighter 50 runs out of fuel, such as gas (for ease ofillustration the term “gas” is used throughout the description, however,the present invention is operable with other types of fuel), when thepressure of such gas falls to, or substantially to, atmosphericpressure. At that point, there is no driving force to push a stream ofgas from inside housing 54. Or, the amount of gas that is pushed fromhousing 54 is too small to either create or sustain a flame. At thatpoint, the user has to inject a pressurized source of gas into housing54 to repressurize the housing with gas.

[0032] Front wall 52 of lighter 50 is cut away to illustrate an inletvalve 64 of lighter 50. Under normal operation, a spring 66 pushes valve64 against a seal plate 68. When the user of lighter 50 wishes to refillthe lighter, the user applies a force via refill container 100 to valve64, which moves valve 64, compresses spring 66 and allows fluidcommunication to exist between an inlet flow path 70 and the inside 72of housing 54. The container 100 includes pressurized gas 104 thatpressurizes the inside 72 of housing 54 through flow path 70.

[0033] For proper filling, a sealed connection between the refillcontainer 100 and the apparatus surrounding inlet valve 64 needs to bemaintained. That is, gas 104 exiting the refill container 100, ifallowed to escape around the outside of the ejection port 106 ofcontainer 100, will escape to atmosphere rather than flow through thenarrow flow path 70. At least a portion of the gas 104, therefore, willnot flow through flow path 70, making the filling of lighter 50inefficient and messy.

[0034] Certain lighters, such as lighter 50, provide a threadedconnection to seal to a refill container. Lighter 50 illustrates femalethreads 74 that are formed around inlet valve 64. A specific refillcontainer (not illustrated) having mating male threads is required tothread into female threads 74, push against valve 64, and create an openflow path of gas from the refill container to the inside 72 of lighter50.

[0035] Container 100 is any known, relatively high pressure gas refillcontainer. For cigarette, pipe and cigar lighters, those containers,collectively referred to as container 100, typically store butane. Thepresent invention, however, is expressly not limited to any particulartype of gas refill. One suitable brand of container is made by Colibri,Providence, R.I. Container 100 includes a shell 102 that stores a drysource of gas 104, such as butane. Container 100 includes an ejectionport 106 that is normally not in fluid communication with the gas 104within shell 102. For example, ejection port 106 can connect to a flange108 that is pushed against top wall 110 of shell 102 via a spring 112.When pressure is applied to the tip of port 106, flange 108 compressesspring 112 and moves port 106, so that an opening 114 through the wallof port 106 allows gas 104 to escape through opening 114 and port 106.

[0036] Without adapter 10, standard high pressure container 100 will notfunction properly with the refill arrangement of lighter 50. Inparticular, when the user presses the tip of port 106 against the tip ofvalve 64, compressing both springs 66 and 112 to establish a flow pathbetween the inside of shell 102 and the inside 72 of housing 54, gas 104will tend to escape around the outside of ejection port 106 and withinfemale threads 74 instead of flowing through flow path 70 into lighter50.

[0037] To remedy the above-described problem and enable standard higherpressure gas refillers, such as container 100, to fill lighters, such aslighter 50, adapter 10 in FIGS. 1 and 2 is provided. FIGS. 1 and 2illustrate that the adapter or transmitter 10 includes a body 14 thathas or defines a connection portion or distributor 16 and a receiver orgrasping portion 18. In one embodiment, connection portion ordistributor 16 includes male mating threads that mate with femalethreads 74 of lighter 50.

[0038] It should be appreciated that connection portion or distributor16 is not limited to having male threads but alternatively has anothertype of device for sealingly engaging a wall or series of wallsextending outside of the inlet valve 64 of lighter 50. For example,lighter 50 could define male threads, wherein connector portion 16defines mating female threads. Other possibilities for the connectionportion or distributor 16 include one or more indentations that receiveone or more O-ring that seals against a smooth bore (not illustrated)defined by lighter 50 around inlet port 64. Or, connection portion ordistributor 16 can define splines on a male or female member that couplesealingly to mating splines defined by a female or male portion,respectively, of the lighter 50. Still further, connection portion ordistributor 16 provides either the tube or the nut and ferrule portionof a ferruled connection, wherein the lighter 50 provides the other ofthe tube or the nut and ferrule. Still further, the lighter 50connection portion or distributor 16 sealed interface can be ahose-barbed, clamped or press-fit interface. Moreover, the interfaceincludes any combination of the above interfaces.

[0039] Body 14 of adapter 10 also includes a receiver or graspingportion 18. Receiver 18 provides a number of uses. First, graspingportion 18 is wider in cross-section than is connection portion ordistributor 16, so that an annular groove 20 can be formed in receiver18 to house and hold an O-ring 22 (FIG. 1). Annular ring 20 is centeredaround the same center line as is a bore or aperture 24 defined byadapter 10, which extends through the adapter. Aperture 24 enablesejection port 106 to pass through adapter 10 and contact inlet valve 64of lighter 50. Grasping portion 18 also enables the user to graspadapter or transmitter 10 to manually insert or remove the adapter intoor out of lighter 50. To that end, the outer surface of grasping portion18 can be knurled, roughened or otherwise adapted to be grasped andturned.

[0040] In the illustrated embodiment, the threads of connection portionor distributor 16 mate with female threads 74 of lighter 50 to disallowgas from escaping around the outside of adapter 10. In a similar manner,O-ring 22 seals around ejection port 106 to disallow gas from escapingaround ejection port 106 and through a clearance area defined by thedifference in radius between aperture 24 and ejection port 106. In thismanner, adapter or transmitter 10 forces gas 104 to flow from container100 through flow path 70 into the inside 72 of lighter 50.

[0041] It should be appreciated that the size of aperture 24 can be madewide enough to allow multiple different diameter ejection ports 106 tooperate with the adapter 10. Importantly, O-ring 12 should be flexibleenough to make a proper seal between an inner wall of the annular groove20 of receiver 18 and the outside wall of ejection port 106, regardlessof the diameter of ejection port 106.

[0042] Adapter or transmitter 10 is made of any suitable material, suchas metal or plastic. Suitable metals include, but are not limited to,steel, stainless steel, aluminum, brass, copper, nickel, and anycombination or alloy thereof. Plastics, such as polypropylene,polystyrene, polyvinylchloride, polyethylene, polycarbonate, polyamide,nylon, acrylic, teflon as well as others, are suitable. Adapter ortransmitter 10 is alternatively wood or ceramic or any combination ofthe above-listed materials. O-ring 22 can be of any suitablecompressible material, such as neoprene, viton, Buna-N (Nitrile),silicone, polyurethane, ethylene polypropylene, butyle and naturalrubber.

[0043] In an alternative embodiment, O-ring 22 can be housed in acircular channel (not illustrated) defined by outside surface 26 ofgrasping portion 18 and form a seal between surface 26 and the outersurface of top wall 110 of connector 100. The O-ring housed in surface26 should be selected so that it does not obstruct the distance thatport 106 can extend past connection portion or distributor 16 wheninserted through aperture 24. This end seal embodiment allows for awider range of diameters for port 106 to operate with adapter 10.

[0044] In operation, the user either threads adapter 10 into lighter 50first and then pushes container 100 through aperture 24 of adapter 10.Otherwise, the operator can place adapter 10 onto container 100 andthread adapter 10 into lighter 50 until the proper threaded connectionis made.

[0045] Referring now to FIGS. 3 and 4, an alternative adapter 30 of thepresent invention is illustrated. FIG. 3 includes a section view takenalong the line III-III of the end view of connector 30 in FIG. 4.Previously, the grasping portion 18 of adapter or transmitter 10extended below the bottom of housing 54 of lighter 50. With that adapterthe user removes the adapter after the use of same. One convenient placeto store adapter 10 is to place adapter 10 over ejection port 106, whichis held relatively firmly in place via O-ring 22, until the user needsto refill lighter 50.

[0046] Adapter 30, on the other hand, has a smaller overall length thandoes adapter 10 and can be permanently or semipermanently installed intothe female threads 74 and lighter 50. Adapter 30 includes a connectionportion 32 and a “low profile” flange portion 34. Flange portion 34is-relatively narrow compared with receiver 18 of adapter or transmitter10. In an embodiment, flange portion 34 is sized so that when adapter 30is screwed into lighter 50, the outer surface of flange 34 is flush orsubstantially flush with the bottom surface of housing 54 of lighter 50.

[0047] Alternative adapter 30 is made of a softer material, such as anysoft plastic or hard rubber and defines an aperture 36 that is slightlyless than the outer diameter of ejection port 106. When ejection port106 is inserted into lighter 50, ejection port 106 presses against theinner cylindrical wall of connection portion 32 and slightly expands thenormal diameter of aperture 36, to create a sealed connection. Flangeportion 34 defines a mounting hole 38 that enables the user to insertand remove adapter 30 from lighter 50. In the illustrated embodiment,mounting hole 38 is sized and shaped to receive a hex driver or Allenwrench. It should be appreciated by those of skill in the art that othertypes and shapes of mounting holes 38 can be provided to perform thesame function.

[0048] Referring now to FIGS. 5 and 6, another alternative adapter 40 isillustrated. FIG. 5 illustrates a cross-section of the adapter 40 takenalong the line V-V of the end view of adapter 40, which is alsoillustrated in FIG. 6. Adapter 40 includes many of the same componentsas adapter 30, such as a housing 48 having the connection portion 32,flange 34 and hex head opening 38. Adapter 40, however, includes analternative aperture 42 that allows a compressible insert 44 to beplaced inside the connection portion 32 of adapter 40. An annularprotrusion ring 46 is provided at either end of aperture 42 to hold thesealing member 44 in place when port 106 is inserted and removed fromadapter 40.

[0049] Adapter 40 allows a hard material, such as metal or hard plasticto be used for the housing 48 of adapter 40. A compressible material,such as any of those described above, which can be more compressiblethan the material used to make adapter 30 is then possible for thesealing member 44. That more compressible material allows for greatervariance in the size of the diameters of port 106 that will operate withadapter 40. Adapter 40, like adapter 30, includes low profile flange 34,so that adapter 40 can be inserted into female threads 74 of lighter 50on a semi-permanent or permanent basis. The sealing member 44 has asmaller inner diameter than the outer diameter of ejection port 106, sothat ejection port 106 deforms sealing member 44 and seals against themember when ejection port 106 is inserted into adapter 40. As before,the connection port portion 32 includes mating threads or other sealingmember that prevents or substantially prevents gas from escaping aroundportion 32 when the user refills lighter 50 using container 100.
